This section should contain new features added in this release. Sample format: + + * **Add a title in the past tense with a full stop.** + + Add a short 1-2 sentence description in the past tense. The description + should be enough to allow someone scanning the release notes to understand + the new feature. + + If the feature adds a lot of sub-features you can use a bullet list like this. + + * Added feature foo to do something. + * Enhanced feature bar to do something else. + + Refer to the previous release notes for examples. + + This section is a comment. Make sure to start the actual text at the margin. + + +* **Added software parser for packet type.** + + * Added a new function ``rte_pktmbuf_read()`` to read the packet data from an + mbuf chain, linearizing if required. + * Added a new function ``rte_net_get_ptype()`` to parse an Ethernet packet + in an mbuf chain and retrieve its packet type from software. + * Added new functions ``rte_get_ptype_*()`` to dump a packet type as a string. + +* **Improved offloads support in mbuf.** + + * Added a new function ``rte_raw_cksum_mbuf()`` to process the checksum of + data embedded in an mbuf chain. + * Added new Rx checksum flags in mbufs to describe more states: unknown, + good, bad, or not present (useful for virtual drivers). This modification + was done for IP and L4. + * Added a new Rx LRO mbuf flag, used when packets are coalesced. This + flag indicates that the segment size of original packets is known. + +* **Added vhost-user dequeue zero copy support.** + + The copy in the dequeue path is avoided in order to improve the performance. + In the VM2VM case, the boost is quite impressive. The bigger the packet size, + the bigger performance boost you may get. However, for the VM2NIC case, there + are some limitations, so the boost is not as impressive as the VM2VM case. + It may even drop quite a bit for small packets. + + For that reason, this feature is disabled by default. It can be enabled when + the ``RTE_VHOST_USER_DEQUEUE_ZERO_COPY`` flag is set. Check the VHost section + of the Programming Guide for more information. + +* **Added vhost-user indirect descriptors support.** + + If the indirect descriptor feature is enabled, each packet sent by the guest + will take exactly one slot in the enqueue virtqueue. Without this feature, as in + the current version, even 64 bytes packets take two slots with Virtio PMD on guest + side. + + The main impact is better performance for 0% packet loss use-cases, as it + behaves as if the virtqueue size was enlarged, so more packets can be buffered + in the case of system perturbations. On the downside, small performance degradations + were measured when running micro-benchmarks. + +* **Added vhost PMD xstats.** + + Added extended statistics to vhost PMD from a per port perspective. + +* **Supported offloads with virtio.** + + Added support for the following offloads in virtio: + + * Rx/Tx checksums. + * LRO. + * TSO. + +* **Added virtio NEON support for ARM.** + + Added NEON support for ARM based virtio. + +* **Updated the ixgbe base driver.** + + Updated the ixgbe base driver, including the following changes: + + * Added X550em_a 10G PHY support. + * Added support for flow control auto negotiation for X550em_a 1G PHY. + * Added X550em_a FW ALEF support. + * Increased mailbox version to ``ixgbe_mbox_api_13``. + * Added two MAC operations for Hyper-V support. + +* **Added APIs for VF management to the ixgbe PMD.** + + Eight new APIs have been added to the ixgbe PMD for VF management from the PF. + The declarations for the API's can be found in ``rte_pmd_ixgbe.h``. + +* **Updated the enic driver.** + + * Added update to use interrupt for link status checking instead of polling. + * Added more flow director modes on UCS Blade with firmware version >= 2.0(13e). + * Added full support for MTU update. + * Added support for the ``rte_eth_rx_queue_count`` function. + +* **Updated the mlx5 driver.** + + * Added support for RSS hash results. + * Added several performance improvements. + * Added several bug fixes. + +* **Updated the QAT PMD.** + + The QAT PMD was updated with additional support for: + + * MD5_HMAC algorithm. + * SHA224-HMAC algorithm. + * SHA384-HMAC algorithm. + * GMAC algorithm. + * KASUMI (F8 and F9) algorithm. + * 3DES algorithm. + * NULL algorithm. + * C3XXX device. + * C62XX device. + +* **Added openssl PMD.** + + A new crypto PMD has been added, which provides several ciphering and hashing algorithms. + All cryptography operations use the Openssl library crypto API. + +* **Updated the IPsec example.** + + Updated the IPsec example with the following support: + + * Configuration file support. + * AES CBC IV generation with cipher forward function. + * AES GCM/CTR mode. + +* **Added support for new gcc -march option.** + + The GCC 4.9 ``-march`` option supports the Intel processor code names. + The config option ``RTE_MACHINE`` can be used to pass code names to the compiler via the ``-march`` flag. + + +Resolved Issues +--------------- + +.. This section should contain bug fixes added to the relevant sections. Sample format: + + * **code/section Fixed issue in the past tense with a full stop.** + + Add a short 1-2 sentence description of the resolved issue in the past tense. + The title should contain the code/lib section like a commit message. + Add the entries in alphabetic order in the relevant sections below. + + This section is a comment. Make sure to start the actual text at the margin. + + +Drivers +~~~~~~~ + +* **enic: Fixed several flow director issues.** + +* **enic: Fixed inadvertent setting of L4 checksum ptype on ICMP packets.** + +* **enic: Fixed high driver overhead when servicing Rx queues beyond the first.** + + + +Known Issues +------------ + +.. This section should contain new known issues in this release. Sample format: + + * **Add title in present tense with full stop.** + + Add a short 1-2 sentence description of the known issue in the present + tense. Add information on any known workarounds. + + This section is a comment. Make sure to start the actual text at the margin. + +* **L3fwd-power app does not work properly when Rx vector is enabled.** + + The L3fwd-power app doesn't work properly with some drivers in vector mode + since the queue monitoring works differently between scalar and vector modes + leading to incorrect frequency scaling. In addition, L3fwd-power application + requires the mbuf to have correct packet type set but in some drivers the + vector mode must be disabled for this. + + Therefore, in order to use L3fwd-power, vector mode should be disabled + via the config file. + +* **Digest address must be supplied for crypto auth operation on QAT PMD.** + + The cryptodev API specifies that if the rte_crypto_sym_op.digest.data field, + and by inference the digest.phys_addr field which points to the same location, + is not set for an auth operation the driver is to understand that the digest + result is located immediately following the region over which the digest is + computed. The QAT PMD doesn't correctly handle this case and reads and writes + to an incorrect location. + + Callers can workaround this by always supplying the digest virtual and + physical address fields in the rte_crypto_sym_op for an auth operation. + + +API Changes +----------- + +.. This section should contain API changes. Sample format: + + * Add a short 1-2 sentence description of the API change. Use fixed width + quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense. + + This section is a comment. Make sure to start the actual text at the margin. + +* The driver naming convention has been changed to make them more + consistent. It especially impacts ``--vdev`` arguments. For example + ``eth_pcap`` becomes ``net_pcap`` and ``cryptodev_aesni_mb_pmd`` becomes + ``crypto_aesni_mb``. + + For backward compatibility an alias feature has been enabled to support the + original names. + +* The log history has been removed. + +* The ``rte_ivshmem`` feature (including library and EAL code) has been removed + in 16.11 because it had some design issues which were not planned to be fixed. + +* The ``file_name`` data type of ``struct rte_port_source_params`` and + ``struct rte_port_sink_params`` is changed from ``char *`` to ``const char *``. + +* **Improved device/driver hierarchy and generalized hotplugging.** + + The device and driver relationship has been restructured by introducing generic + classes. This paves the way for having PCI, VDEV and other device types as + instantiated objects rather than classes in themselves. Hotplugging has also + been generalized into EAL so that Ethernet or crypto devices can use the + common infrastructure. + + * Removed ``pmd_type`` as a way of segregation of devices. + * Moved ``numa_node`` and ``devargs`` into ``rte_driver`` from + ``rte_pci_driver``. These can now be used by any instantiated object of + ``rte_driver``. + * Added ``rte_device`` class and all PCI and VDEV devices inherit from it + * Renamed devinit/devuninit handlers to probe/remove to make it more + semantically correct with respect to the device <=> driver relationship. + * Moved hotplugging support to EAL. Hereafter, PCI and vdev can use the + APIs ``rte_eal_dev_attach`` and ``rte_eal_dev_detach``. + * Renamed helpers and support macros to make them more synonymous + with their device types + (e.g. ``PMD_REGISTER_DRIVER`` => ``RTE_PMD_REGISTER_PCI``). + * Device naming functions have been generalized from ethdev and cryptodev + to EAL. ``rte_eal_pci_device_name`` has been introduced for obtaining + unique device name from PCI Domain-BDF description. + * Virtual device registration APIs have been added: ``rte_eal_vdrv_register`` + and ``rte_eal_vdrv_unregister``. + + +ABI Changes +----------- + +.. This section should contain ABI changes. Sample format: + + * Add a short 1-2 sentence description of the ABI change that was announced in + the previous releases and made in this release. Use fixed width quotes for + ``rte_function_names`` or ``rte_struct_names``. Use the past tense. + + This section is a comment.
